GAS-BURNER CONTROL.

Application filed. May 8,.

This invention relates to iniproven'ients in gas burner controls. Q

An object of this invention 18 to proyide a device for controlling the flow of gasln a pipe or conduit to a gas burner, which can be remotely controlled.

Another object of this invention is to provide a. device for controlling the flow of fuel orgas to a burner, which is ot simple construction and which is so arranged that a low, intermediate or high fire can be regulated by means of the remote control which consists of a single switch.

A turther object of the invention is to provide means associated with the valve or burner control for indicating which ot the three possible degrees of tire is tnirning at the remotely located switch.

\Vith the foregoing and other olnects in view which will be made manifest in the following detailed description and specifically pointed out in the appended claims, reference is had to the accon'ipanying drawings for an illustrative embodiment of the invention, wherein:

Figure l is a side elevation of the in1- proved gas burner control, the cover being shown as broken away and removed,

Fig. 2 is a vertical section taken substantially on the line 22 of Fig. 1,

Fig. 3 is a horizontal section taken sub stantially on the line 3-3 of Fig. 1, and

Fig. 4t is a view-similar to Fig. 1, the device being shown as having been actuated so as to n-oduce a low tire. whereas Fig. 1 shows the device in completely closed position.

Referring to the accompanying drawings wherein similar reference characters designate siinilarparts throughout, the device is illustrated as having a box-like casing having a bottom It), a top ll, a back 12 and side walls 13 and l4. A cover 15 constituting the front wall is rcn'iovably secured upon the casing as by screws 16. Upon the back of the *asing there is mounted a valve body t"? secured upon the back as by screws 18. This valve bodv has recesses 19 'iorn'ied in its ends which are interiorly threaded so that the valve body may be connected to the adjacent ends oi pipe sections forming a gas line or other fluid line.

Three bores 20, 21 and 22 are formed in the 'alve body 17 and these bores are parallel to each other. The bores 21 and 22 are in the same horizontal plane, whereas the bore 1925. Serial No. 28,947'.-

is in a plane above the plane containing the bores 21 and 22. Two stems 23 and 24 have their forward ends disposed within the casing and extend through the back 12 and into the valve body 17. The stem 23 extends through the bore20 and has an aperture formed therein, as ind1- cated at 25, which upon rotation of the stem 23is adapted to be brought into register with the bore 20, permitting gas to flow in the gas line through the bore 20. The stem 2% is also rotatable in the valve body 17 and has two apertures formed therein which are adapted to be brought into register with the bores 21 and 22. In this manner the stem 24 alsoprovides means. for opening and closing the. gas line.v It will be understood that if the bores 21 and 22 are closed, and the'bore 20 is open,a small amount of gas will be allowed to flow in the gasline. It the bore 20.;is closed and the bores 21 and 22 are open, a larger amountot gas will be allowed to flow in the gas line; and inv such position, there will be produced an intermediate fire When all of the bores are open, the maximum amount of gas will be allowed to flow, poducing a high fire.

The stem 23 carries an annular plate 26 thereon, which plate is disposed within the casing. The plate is shown as slightly spaced fromthe back 12 and has four studs indicated at 27, 28, 29 and projecting torwardly therefrom. The studs 28 and 29 are preferably the same length and are some what shorter than the studs 27 and 30 for a. purpose hereinafter to be described. These studs are arranged adjacent the edge of the plate 26 and are angularly disposed 90 deg. apart. They serve to provide projections carried by the stem 23. A pin 31 extends diametrically through the stem 23 and this pin is arranged forwardly of the forward ends of the longstu'ds 27 and'30. This pin serves'to provide diametrically op posed contacts upon thestem 23 for a pose hereinafter to be described.

' I provide means for rotating the stem 23 so as to open and close the bore 20, which means is operable at a location remotely.

situated from the gas burner control. This means consists of a solenoid 32 which is disposed within the container, or casing adjacent its upper corner. Suitable wires are connected to the solenoid 32 through a source of current and to a remotely locatedswitch,

p urnot shown. A core 33 has its upper end i slidable within the solenoid and serves as an armature adapted to be attracted by the solenoid. The lower end of the core 33 is slidable in a sleeve 34 which is secured as by screws 35 to the bottom of the casing. The sleeve 34 has a slot 36=tor1ned therein. The bot-tom ot the core 33 has a slot- 37 in which is pivoted a pawl 38 as upon a pin The operation of the means for rotating the stein 23 is as follows: hen the remotely located switch is closed, establishing an electric circuit through the solenoid the solenoid will become energized and lift the core or armature 33. The upper end of the awl '38 en a es the stud and moves or rotates "the stem 23 from the position shown in Fig. 1 to the position shown in Fig. 4, thus rotating the stem from closed position as shown in Fig. 1. to open position, as shown in Fig. 4. The remotely located switch may be in the term of a button or the like and when it is allowed to open so as to break the circuit through the solenoid 32,

a: the core or armature 33 will fall under gravity, the pawl 38 swinging against the side of the core 33 as 1t slidcs'over the stud 29.

. which has been brought into the position previously occupied by the stud 30. It will be noted that the bottom edge of the pawl 38 flush with the bottom of'the core 33 when the pawl is in the position shown in Fig. 1. VV'h'en the pawl 38 is "swung against the side of the core 33, the corner 40 projects slightly below the bottom of the core and as the .core 33 strikes the bottom 10 ot the casing,

the pawl 38 will be forcibly thrown from the side of the core 33 into the position shown From 'an inspection of Fig. 4, it will be 'a-ppreciated that when the core 33 is in. its uppermost position, the stud 29 engages the side edge 38 of the pawl 38 so that the pawl serves as a stop, limiting the rotation oi the stem 23 to "a quarter of a revolution upon "each movement of the armature 33. The pawl 38 is slidable in the slot 36 formed in the sleeve 34 and in this manner rotation of the core 33 is prevented. It will be understood that every time the switch is closed so as to energize the solenoid 32, the core 33 will be lifted and the pawl 38 will engage whichever stud upon the plate 26 is in the position. occupied by the stud 30 in Fig, 1.

In this manner the stem 23' is rotated a quarter of a revolution every time that the switch is closed.

The above described means produces rotation of the stem 23 so as to open and close tllQ'bOlG 20, which provides the low tire in the burner. 'The means for rotating thestem 24 is as follows: Between the plate 26 and of two opposed projections 42 and 43, which have'exterior cylindrical surfaces. Notches 44 define the rojections 42 and 43 and are arranged diametrically opposite each other. Studs 45 project rearwardly from. the plate 26 oppos'te the notches 44. Upon the forward end ot the stem 24 there is mounted a type of Geneva gear, which consists of a plate-like body 46, which is disposed behind the plate 26 and which has two diametrical grooves 47 formed in its forward face. The plate-like body 46 is cruciform in plan, and simulates a Geneva cross so that the plate 46 can be properly termed a Geneva gear. The stem 24 with the Geneva-gear 46 are so arranged that the cylindrical surfaces 48 formed upon the periphery of the body 46 are complementary to the cylindrical surfaces provided upon the n'ojec-tions 42 and e 43. The studs 45 are so arranged upon the back side of the plate 26 as to enter any of the grooves 47. hen the stem 23 is rotated but a 'quz'irter of a revolution from the closed position shown in Fig. 1 to the open position shown in Fig. 4. the stud 45 will have ro tated'96 deg. and will be opposite the right hand end of the horizontal groove 4-7 upon the plate 46. During the next quarter revolution which swings the stem 23 from the position shown in 4 to a closed position which position will. be after the stem 23 has rotated 180 dog. from the position i'aihown in Fig. 1, the stud 45 enters the groove 47 and swings the stem 24 and the plate 46 through a quarter of a revolution. During the next quarter revolution of the stem 23, the stem 24 will "not be rotated, but will be lrcpt stationary because ot the engagement between the cylindrical. surfaces 48 and the quarter revolution of the stem 23, the stem '24 will. again be rotated a quarter of a revolution, and in this manner it will be appreciated that the stem 24 rotates one quarter of a revolution during every alternate quarter revolution oi. the stem 23. r

'The cycle of evcntst'or the two stems 23 and 24 theret'ore as tollows: Fitartingr in the position shown in Fig. 1, in which all of the bores 20, Q1 and 22 are closed, the first quarter revolution of the stem 23 opens the bore 20, the stem 24 remaining stationary during this movement. During the second quarter revolution of the stem 23, the bore 20 will be closed again and the stem 24 rotated a quarter of a revolution to open the bores 21 and 22. In this manner the amount of gas flowing in the gas line after the stem 23 has been twice rotated a quarter ot' a revolution will be twice as great as when the bore 20 is open, thus providing an interme diate tire. During the third quarter revolullO tion of the stem 23, the stem 24 remains sta- 'tiona'ry, leaving the bores 21 and 312 open,

and the stem 23 will be rotated in such a position as to open the bore 20. In this position all of the bores are open and a high fire is produced. During the fourth revolution the stems 23 and 24. are both rotated 90 deg. and all the bores are closed. In this manner a. low, ii'itermedia'te and high tires can be produced by closing the remotely located switch the required number of times. In a gas control of this kind, it neces sary to provide some kind of means for indicating the position oi the stems 23 and 24 so that it may be determined whether a low or intermediate or high tire is burning. \Vithin the side wall 13 ot the casing there are mounted two LG'SlliGDlJ contacts indicated at 50 and 51. The contact 50 is so an ranged as to clear the short studs 28 and 29 upon the plateQG, but will engage the ends of the long studs 27 and 30, The contact 51 arranged forwardly oi the contact 5t) and is adapted to be engaged by the ends ofthe pin 31. The long studs 27 and provide two contacts upon the stem 23 which are 90 deg. apart and which are adapted to engage the contact 50. The pin 31 provides two contacts upon the stem 23 which are 180 deg. apart and which are adapted to engage the contact 51. A light is connected in series with each contact and 51. These lights are mounted adjacent the remotely located switch and are coi'i'nected through a suitable source of current to the casing which serves as a ground as shown in Fig. 3. By tracing out the cycle of events, it will be appreciated that in the position shown in Fig. 1, neither of the con tacts 50 or 51. a e engaged and the lights will there-tore not burn, indicating that no gas is turned on. In the position shown in Fig. 4t, one end of the pin til-is engaging the contact 51, so that one light is burning, which light designated so as to indiate that the bore 20 is open. After the second quarter of a revolution has been made, this end of the pin 31 will disengage the contact 51 and the stud 27 will engage the contact 50, causing the other light to be illuminated, indicating that the bores 21: and 22 are open and that an intern'iediate tire is burning. After the third quarter revolution. the stud ill) and that end oi" the pin 3!. which is above it will have been rotated so that. both of the contacts 50 and 51 will be engaged, thus causing both of the lights to burn siinultancously, indicating that all of the bores are open and that a high tire is burning. 7

From the above it will be appreciated that an improvec gas burner control is provided which can be remotely operated and which has indicating means tor indicating the kind of fire burning. The device is so constructed as to be simple in operation, having a comparatively few moving parts and which will not get out of order. By mounting the pawl 38 directly upon the core 33, someuof the parts employed in prior constructions are eliminated. It will be understood that the exact construction shown does not neces sarily have to be employed. For example, the projections upon the stem 23 afforded by the studs i i, 28, 29 and 30 can be provided in other manners, it desirable. .By arranging the valve hodyl'lin a horizontal position. across the back 12, the device can be mounted upon any horizontal portion of a gas line and rotated in such a position that the core 33 is vertically disposed and the solenoid 32 is arranged above it, so that the core 33 will be gravity retracted int-o its initial position when the solenoid 3:2.is deenergized. If :lound desirabldsprings can be employed for returning the core into its initial position and the device maybe so arranged as to be in a horizontal position.

.It will be understood that, it is not necessary to employ both of the stems 9.3 and 24, as the stem 23 can be used in connection withsolenoid 32, the slidable core 33 and the pawl 38, without employing the stem 24. In other words, the stem 23 can be used alone with the actuating mechanism which rotates it one quarter of a revolution. at a time. I

It will also be understood that the stems 23 and 24; can be used in conjunction with each other without employing the specific actuating mechanism as shown for rotating the stem 23 one quarter of a revolution at a time. a

It will be understood that various changes may he made in the detail of construction without departing from the spirit or scope of the invention as defined bythe appended claims. i
